Investigators said the victim was shot in the back of the head near 36th Street and Broadway about 10:30 p.m. Tuesday. He was later identified as Lionel S. Hernandez, 47, of Kansas City.

Police said Hernandez and another employee, Jeffrey Hulett, walked across the street to a convenience store to buy lottery tickets.

According to court documents, when police took Hulett into custody, he told them that the gun in his possession was the gun used to shoot Hernandez. Police said Hulett told them that he planned the shooting in advance and because Hernandez had "crossed the line."

Police said Hulett told them he lured Hernandez outside with an offer to buy him lottery tickets and then shot him point blank.

Relatives of the three people killed in last year's shootings at the Overland Park Jewish Community Center and a nearby nursing home have a plan to remember their loved ones with random acts of kindness.
